The National Marine Electronics Association (NMEA) has released its latest protocol, the NMEA OneNet® Standard, Version 1.000.
This is an open industry standard based on Internet Protocol Version 6 (IPv6) and the IEEE 802.3 Ethernet Local Area Network. The standard brings together years of committee efforts and is designed for standardized IP networking of marine electronic devices on and off the vessel.
OneNet provides a common network infrastructure for marine electronic devices and/or services on IPv6. All OneNet application protocols, such as NMEA 2000® PGN messages, are designed to use a standard IPv6 network protocol stack. The NMEA OneNet Committee utilized many existing standards, including RFCs (Requests for Comments) published by the Internet Engineering Task Force (IETF). This will significantly reduce implementation cost and ensure compatibility with existing TCP/IP networks around the world.
The primary features and goals of OneNet
NMEA 2000 data transfer over IPv6 in a standard format
High-bandwidth applications such as radar, video and more that are not possible via NMEA 2000
Support Ethernet and TCP/IP at 1 gigabit and faster speeds
Utilize standardized connectors (RJ-45 and X Coded M12) depending on installation
Robust, industry-standard cybersecurity requirements
NMEA 2000 gateway compatibility
Mandatory device & application certification by the manufacturer, they then verified by NMEA
